In recent years, the Internet of Things (IoT) has attracted much attention. The world views the IoT as the potential business opportunities in high-tech industries and invests a lot of resources in research, development and promotion. The IoT is broadly utilized to improve the quality of human’s life and make it more convenient. However, there are some differences between the wireless communication technology (such as Bluetooth, ZigBee, Wi-Fi, infrared, etc.) used in common electronic device markets. As a result, the real-time information and device status cannot be integrated effectively which enhance the difficulty of the integration of Internet of Things in heterogeneous network. In this thesis, we intend to design a gateway using the Internet of Things, namely ‘Heterogeneous Gateway’, which can integrate various smart objects of the wireless communication technology. This gateway can solve the coexistence of heterogeneous network by conducting any smart objects to exchange real-time information and monitoring status in order to enhance the efficiency and quality of network transmission.
